HIS Radeon HD 6850 1GB Video Card w/ 1120 Shaders Overclocked
 

So we started with the boring stuff and checked out the HD 6850 and HD 6870 on their lonesome against a bunch of other cards. We began to have a bit of fun when we started pairing the cards together. There's no denying, though, that for most people Crossfire isn't an option, be it too expensive or just not really feasible.

So now it's time to get into the fun stuff and the stuff that people are going to be interested in as it will cater to a larger audience of HD 6850 users, and that is overclocking. We love it; there's nothing better than getting more performance for the extra cost of nothing. So the question is, what kind of overclocking potential has the HD 6850 got? And when overclocked, where do we see the model sit? Since we've already looked at the HIS HD 6850 when we tested Crossfire performance, here we will just get straight into the overclocking side of things and see what we have achieved.
